With the amplification of digitization, the surge in multimedia content, such as text, video,
audio, and images, is incredible. Concomitantly, the incidence of multimedia tampering is …

Quantum image representation plays an important role in quantum image processing. In this
paper, a bitplane representation of quantum images (BRQI) is proposed, which uses (n+ 4) …

In this paper a new technique of dual image watermarking is proposed for protection of
ownership rights which utilizes salient properties of homomorphic transform (HT), discrete …

Recently, several quantum image watermarking (QIW) schemes have been introduced, but
they cannot be implemented in today's quantum systems due to lack of sufficient number of …

An enhanced quantum watermarking technique is developed by integrating the quantum
Haar wavelet transform (QHWT) with Qsobel edge detection to increase the invisibility and …

In some image processing algorithms, such as those for image feature extraction and
segmentation, filtering is a significant pre-processing step to remove noises and improve …

As an important way to protect copyright by embedding watermark in digital images,
quantum watermarking catches more and more attentions. In this study, a novel quantum …

In the development of quantum image steganography, the visual effect of the image has
always been the focus of scholars' research. Based on the classical Gray code algorithm …

Quantum image steganography has attracted considerable attention in recent years. The
majority of existing algorithms do not simultaneously have excellent imperceptibility, high …

A novel and traceable quantum steganography scheme based on pixel value differencing
(PVD) is proposed. In the proposed scheme, a quantum cover image is divided into non …
